The preferred form of eens'bincticn illustrated in the Eirewings comprises a reetangular metallic casing 1 which is pm vicied with a removable lid 01 closure 2 as shown. At its upper end casing l is provided with inwardly "projecting locking lugs and closure 2 is proviiecl with locle ing 4 adapted to engage lugs 3 and prevent the olirect outward removal of the (301 responding end ssiclelesnre a will be readily unclersteod, said lugs being so airiengedns to permit the preps-c positioning ei closure 2 by tiltingtlie ffhereel.

Fuel supply pipe 18 is the ordinary fuel supply pipe for geselene engine, so that When valve 16 in one posi'sien the fuel pass to the eerlinreien ei the engine bui, when n. nesition the passage of fuel in airmer of engine is cut oil. Ev 'rengemm-fi; will be ebservee ptlieiz 8 is in the position indicated in this .1 when. (ism renileifwl nnpessible.

fllell 1Q cerriese metallic eenneclring strip en in iiceteel 02 the ei leclae'cl in that pesition by simply cli'e ppmg 3 vile elesini'e 9: may be readily placed in p0 an engine, so that when bolt 10 is in its de.

pressed position as shown in Fig. 2 the primary circuit of'the spark coil is broken and when bolt 10 is in its elevated position as indicated in Fig. 3 the primary circuit through the spark coil is or may be closed.

By this arrangement it will be observed that when cam 8 is manipulated to close pipe 18 against passage of fuel, the primary circuit of the engine is also broken, thus eii'ectually preventing starting of the engine due to the absence of a spark. l

A combination 01': "is arranged in casing 1 in operative relation with bolt 10, said combination lock comprising the usual notched disl'is 23 which are operatively connected with an operating handle Q Lso as to facilitate manipulation of said disks to set the combination to permit elevation of bolt '10 as will bereadily understood by those familiar with combination locks. The specificform of combination lock is old and well known constituting no part of my invention and needs no further description here.

In use the casing 1 is secured to the ordinary dash board of an automobile and contacts 20 connected in series in the primary circuit of the engine. Valve casing 17 is inserted in the fuel supply pipe of the engine as will be readily understood. When it is desired to lock an automobile against unauthorized removal, handle 7 is manipulated to depress bolt 10, thereby breaking the primary circuit so as to prevent the Formation of a spark and also closing the fuel supply pipe so as to out 01f the supply of fuel from the engine. The combination is then thrown so as to prevent return of bolt 10. This will 'efiectually prevent unauthorized starting of the engine and consequent removal of the automobile. When it is desired to star-t the car theQcombination is manipulated to permit elevation of bolt 10, said combination being only the knowledge of one authorized to operate thecar,

it can only be properly set by such a person.

Then handle 7 is manipulated to cause cam 23 to elevate bolt lO'thus closing the sparking circuit and opening the fuel supply pipe when the car is ready for operation in the usual manner. In case-it is desired to inspect the interior of casing 1 for repairs or otherwise,.cam 8 is moved to the position' indicated. in Fig. 3 whereupon closure may be removed by the removal of screws l2. It will be observed however that the clor sure 2 cannot be removed when, the locking "device has been set at safe position, owing to the engagement of cam 8 with looking shoulders 11, thus preventing tampering with the car by removing the closure 2.

' While I have illustrated and described the preferred form of construction for carrying my invention. into effect, this is capable of variation and modification without departing from the spirt of the invention. I,

therefore, do not wish to be limited to the precise details of construction set forth. but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
